MB85RS2MTYPNF-GS-AWERE2

Memory IC Overview

The MB85RS2MTYPNF-GS-AWERE2 is a 2Mbit (256K x 8) ferroelectric random access memory (FeRAM) integrated circuit manufactured by RAMXEED. It utilizes a Serial Peripheral Interface (SPI) operating at frequencies up to 50 MHz and supports SPI modes 0 and 3. The device operates within a supply voltage range of 1.8V to 3.6V and functions across an ambient temperature range of -40°C to +125°C. It is housed in an 8-pin plastic SOP package with a 150mil lead pitch.

Memory IC FAQ

Is the data in the special sector region guaranteed after reflow?

Yes, data storage in the special sector region is guaranteed after three times reflow based on JEDEC MSL-3 standard conditions.

What is the maximum operating frequency of the SPI interface?

The maximum operating frequency is 50 MHz for most commands, though it is limited to 40 MHz for READ commands and 10 MHz for SSRD commands.
